SPECIFICATION forming part of Letters Patent No. 611,121, datedSeptember 20, 1898. Application filed May 8, 1897. Serial No. 635,650.(No model.)

To ctZZ whom it may concern.-

Be it known that we, JAMES W. HENRY and ALEXANDER GUNN, of Wallace, inthe county of Shoshone and State of Idaho,have invented a new andImproved Grain-Bagging Machine, of which the following is a full, clear,and exact description.

The object of the invention is to providea new and improvedgrain-bagging machine arranged to properly support and hold open anempty bag or sack during the filling operation, to close the open end ofthe bag by sewing after the bag is filled with the grain, and to finallydischarge the filled and closed bag from the machine.

The invention consists of such parts and combinations as will be fullydescribed hereinafter and then defined in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Fig. 15 is an enlarged side elevation of the needle with parts insection. Fig. 16 is a side elevation of the tension device for thethread in the needle; and Figs. 17, 18, 19-, and 20 are sectional viewssimilar to the left-hand portion of Fig. 7, the views showing the partsin various positions to illustrate the operation thereof.

Theimproved machine is mounted on asuitably-constructed frame formedwith a base A, posts or columns A, and a top plate A in which and thesaid base- A is secured a vertically-disposed shaft B, on which ismounted to turn the bag-carrier C,provided at its lower end with a table0, resting on a collar B, attached to the shaft '13. The bag-carrier isalso provided with a top resting on the collar B secured to the shaft B,and the said top is connected with the table O by adjustable standards,each formed of two pieces C 0 fitted to slide one on the other andadapted to be secured together by bolts 0 after the desired distance isobtained between the table G and the top 0 It is understood that when anadjustment is made to increase or diminish the distance between thetable 0 and the top 0 the standards are adjusted and the table 0 ismoved up or down with the collar B adjusted accordingly on the shaft B.This arrangement isnecessary for different-sized bags to be filled withgrain, the said bags resting with their lower ends on the table 0 andthe upper ends or the mouths of the bags being engaged by bag-holders,as hereinafter more fully described.

The bag-carrier O is rotated by mechanism driven from the maindriving-shaft D, journaled in suitable bearings on the top plate A ator,andon the said shaft is also secured an eccentric E, connected by itseccentric-rod E with a block E fitted to slide in a suitable casin g Aattached rigidly to the main frame.

In the block E is formed an openingE into which extends one end of abellrcrank lever E fulcrumed in an opening formed in a second block 6,also sliding in the casing A The block F. is formed with a recess 6 inits I oo upper side, into which projects a pin 6 fixed in the block c.The blocks 6 and 6 therefore have independent sliding movement limitedby the slot e and pin 6 The bellcrank is provided with a tooth E adaptedto engage the notches 0 formed on the peripheral edge of the top C ofthe bag-carrier O, as shown in Figs. 7and 17 to 20. The rod E, beingreciprocated by the eccentric E, drives the block E rapidly back andforth in the casin g A The block 6, being also slidable in the casing Aand carrying the bellcrank E is moved with the block E As the block Emoves leftward from the position shown in Figs. 7 and 17, it movesindependently of the block e until the pin 6 is engaged with theright-hand end of the recess e. WVhen this takes place, the bell-crank1ever 6 will have been thrown to engage its joint F. with one of thenotches G of the top 0 of the table. Then when the block e begins to runwith the block E the bell-crank lever itself will be advanced leftwardand the top 0 will be driven. Fig. 18 shows the position of thepartsimmediately before the block (2 begins to move. Fig. 19 shows the twoblocks 6 and F. moved leftward after having advanced the top 0 and Fig.20 shows the parts in the position which they assume when the block Ehas been partly recovered and immediately before the recover of theblock e begins. The casing A is provided with a spring-pressed pawl E,which engages the notches C of the top (3 to prevent retrograde movementof said top.

The top C of the bag-carrier O is out out at four places to formopenings, in which are arranged four ba -holders F, each formed with afixed segmental jaw F, integral with the top 0 and the two movablesegmental jaws F and F pivotally connected at their ends to the top 0and pivotally connected at their inner or free ends with a radial bar G,fitted to slide in suitable bearings C formed or attached to the top 0The pivotal connection between the bar G and the movable jaws F and F isby means of a pin in the bar G, the said pin passing through elongatedslots in the free ends of the jaws F and F so that on moving the bar Gradially inward or outward the jaws F and F are opened or moved into aclosed position, as illustrated in Fig. 1.

Each of the bars G is provided near its outer end with a depending lugG, carrying a radially-extending rod G fitted to slide with its innerend in a bearing formed on the under side of the top C (See Fig. 2.) Onthis rod G is coiled a spring G resting with one end against theaforesaid bearing and with its other end abutting on the lug G. Thespring G serves to move the bar G into an outermost position, so as tohold the movable jaws F and F normallyin a closed position, as indicatedat the left and right in Fig. 1. The lug G of each bar G is alsoconnected with one end of a chain G passing around pulleys G and G,journaled on the top 0 the chain extending downwardly from the pulley Gto connect with a vertically-disposed arm G fitted to slide verticallyin suitable bearings attached to the standard parts C previouslymentioned, each arm G being provided at its lower end with a foot-pieceG adapted to be engaged by the foot of the operator to press thefoot-piece downward to impart a sliding motion to the arm G in the samedirection, so as to exert a pull on the chain G to pull thecorresponding bar G inwardly, so as to open the movable jaws F and F asindicated at the front and rear in Fig. 1. When the front holder F hasits jaws F and F in an open position, as shown in Fig. 1, then the bagisattachedwith its mouth to the said jaws by means of fixed pins F held onthe movable jaws F and F and by pins F forming part of the fixed jaw F,but laterally movable thereon, as hereinafter more fully described.

When the bag has been placed in position on the holder, the operatorreleases the pressure on the foot-piece G to permit the spring G to pushthe bar G, with its holder, downward to close the jaws. When the carrierG is now rotated or given a quarter-turn, the closed jaws move into theposition shown to the left in Fig. 1. A friction-roller G on top of thebar G now moves in engagement with a cam G fixed to the under side ofthe top plate A of the main frame, and when a quarter-turn is now givento the carrier 0 this friction-roller G in traveling along the fixed camG causes the bar G to slide inward, so as to bring the jaws F and F ofthis holder into an open position at the time the holder moves into arearmost or filling position, as indicated in Fig. 1. The bag is nowfilled, and when this has been done another quarterturn is given to thebag-holder C, so that the friction-roller G passes off the cam G topermit the spring G to act on the bar G and close the jaws F F so as tohold the mouth of the bag over the grain contained in the bag during thetime the bag is closed by sewing, while the bag passes from the fourthposition back to the first position at the front of the machine.

Each of the fixed jaws F forms an integral part in the form of anupwardly-extending segmental flange of the ring C of the top C of thebag-carrier, as plainly indicated in Figs. 2 and 5. The pins F extendparallel one to the other and pass through openings in the jaw F, andthe set of pins for each jaw are attached at their inner ends tosegmental blocks F fitted to slide on top of the ring C in the rear ofthe jaw F. 011 the top of each block F are formed angular recesses Feach engaged by a pin H, depending from a seg ment I'I, fitted to slideon the top of the ring (3 and held in place thereon by bolts 1-1 passingthrough segmental slots H formed in the segment H. On the under side ofeach seg ment H is formed a recess H (see Figs. 5 and 6,) engaged-by thewrist-pin of a crank-arm H formed or secured on the upper end of.

the shaft H arranged vertically and mounted to turn in suitable bearingsin the ring G On the lower end of the shaft H is secured a handle Hadapted to be taken hold of by the operator to impart a turning motionto the shaft H so as to cause the crank-arm H to impart a sliding motionto the segment H, so as to shift the block F inwardly or outwardly,according to the motion given to the handle H The block F by movingoutwardly pushes the pins F a suitable distance beyond the inner face ofthe fixed jaw F, so as to securely engage the web or fabric of the mouthof the bag to securely hold the mouth of the bag in an open positionwhen the jaws F and F move inward, carrying along the inner part of theweb or fabric of the mouth of the bag to hold the mouth open during thefilling operation. When the block F moves outwardly, the points of thepins F are partly withdrawn in the fixed jaw F, and when this takesplace the bag is in a filled position at the front of the machine, andthe withdrawing of the pins disengages the fabric of the bag, so as torelease the closed-up mouth to allow the removal of the bag from thetable C. Each of the pins F is preferably provided on top with atransverse notch F to retain the fabric of the bag in place as long asthe pins are in an outermost position and during the time thebag isbeing filled.

The device for sewing up the mouth of the bag while the latter passesfrom the fourth to the first position is arranged as follows, specialreference being had to Figs. 8 to 14.

On the end of the shaft D is'secured a wheel I, formed on its inner facewith radial grooves I and I engaging blocks 1 and 1, respec tively,extending with their outer endsinto openings J and J respectively,formed in the segmental needle J. The blocks 1 and I are provided neartheir inner ends with pins 1 and I", engaging the cam-groove K of a diskK, provided with a hub K rigidly supported on the main frame and throughwhich passes loosely the forward end of the shaft D. In the disk K isformed an annular race K for the segmental needle J to travel in, thelatter being carried around by the,blocks I and 1 as the shaft D isrotated, the said blocks being carried around by the wheel 1, beforementioned. In the under side of the disk K is formed atransversely-extendin g recess K through which passes the doubled-upedge of the mouth of the bag, the said edge extending above the closedjaws F F F as the latter pass from the third to the fourth position andfrom the'fourth position back to the first position, as will be readilyunderstood by reference to Fig. 1. Now during the time the needle Jpasses through the doubled-up edge of the bag the corresponding block Ior- I is moved inwardly by the action of the pin I or I traveling in thecam-groove K, the latter being shaped so as to move the correspondingblock into an innermost position at the time the block passes over therecess K Thus both blocks are always in engagement with the needle J forpushing the same around in the race K except when one of the blocks 1 Iis drawn inwardly to pass the recess K". The forward end of the needle Jis provided with a point J and the rear end thereof is made hollow andprovided with a hinged plate J held in an open position by a spring Jbut adapted to be opened to place the coil of thread L in position inthe hollow part of the needle, as shown in Fig. 15.

The sewing-thread is doubled up and formed into a coil with thedoubled-up middle portion extending lengthwise through the coil and withthe outer loop L adapted to hook upon the hook K of the plate Kfulcrumed on the ring K at the side of the recess K. The doubled-up endsof the coil of thread L pass through a tension device N, fitted into theouter end of the hollow portion of the needle to give the desiredtension to the thread passed through the fabric material of the bag. Thetension device is formed with two longitudinally-extending ellipticsprings N N having their convex sides inward toward each other, as shownin Fig. 16.

Now when the several parts are in the position, as shownin Fig. 15, andthe needle iscaused to travel in the raceK then the needle passesthrough the bag material and the loop L of the sewing-thread at thehook- K and as the cord is now drawn tightlythe loop slips off the hookK and locks the first stitch on the bag. The cord or thread is carriedthrough the bag material within the needle and over it, so as to form asuccession of overstitches. The coils or spools of threads L are soformed that the thread is unwound from the forward end and. drawnthrough the center of the coil,

the outer coil being the last to unwind. 1 The adapted to formback-rests for the sides of the bags. The upper end of each board 0 iscon nccted by a short chain 0 with the corresponding chain G so thatwhen the treadle or foot-piece G is pressedby the operator and thecorresponding jaws are opened then a pull is exerted by the chain G onthe chain 0 to tilt the upper end of the dumping-board O inward and thelower endvoutward to throw the filled and closed bag off the table 0, asshown by dotted line at the left of Fig. 2. The chain 0 is somewhatslack to permit the jaws to open before the board commences to throw thebag off.

The operation is as follows: When the several parts are in position, asillustrated in Fig. 1, the jaws F and F at the front of the machine areopened by the operator pressing the corresponding foot-piece G A bag isnow placed on the pins F and F after which the operator removes his footfrom the footpiece G to permit the corresponding spring G to close thejaws F and F, as previously explained, so that the two sides of themouth of the bag are pressed against each other or clamped between thefixed jaw F and the movable jaws F F The operator now shifts the beltfrom the loose to the fast pulley D, so that the shaft D is rotated, anda rotary motion is now given to the bag-carrier C by the mechanism abovedescribed to move the bag from the first to the second position, so asto bring the friction-roller G in engagement with the cam G In thesecond quarter-revolution of the bag-carrier the jaws F F are opened, soas to hold the mouth of the bag open at the time it passes to the thirdor rearmost position, and while in this position the bag is filled withthe grain, it being understood that the belt is shifted from the fast tothe loose pulley after each quarter-revolu tion of the bag-carrier hasbeen made, so as to give sufficient time for filling the bag. During thenext quarter-revol ution-that is, after the bag has been filled-themovable jaws F F close by the action of the spring G at the time thefriction-roller G passes off the cam G so that the mouth of the bag isclosed when the bag arrives at the fourth position. The projecting edgeof the mouth of the bag above the jaws now passes into the recess A andduring the first quarter-revolution the needle J is caused to travelaround in its circular race K to sew the edges of the mouth of the bag,as previously explained. Then the bag finally arrives at its firstposition, its

mouth is sewed up, and the operator now turns the handle H so as towithdraw the pins Fiand then presses the foot-piece G so as to open themovable jaws F and F As the movable jaws F and F swing inward theirteeth F move out of themeshes of the jaws of the fabric of the bag, andas the pins F have been withdrawn they are also out of engagement withthe fabric, and consequently the mouth of the bag is wholly free fromthe jaws, and at this time the dumping-board 0 turns, as beforeexplained, so as to throw the bag 01f the table 0. Another empty bag isnow inserted in the jaws and hung on the pins F F, after which theoperator releases the foot-piece G to permit the jaws to close, asbefore explained.
